This is pretty cool. Thanks for the link.
That is a very cool compilation. At first I thought that it would be simply a mash-up of saved and thrown together tutorials from all over the web (especially polycount) but I was pleasantly surprised. I am tempted to get that thing printed so I can have it as a physical thing.
Hopefully they keep up releasing or updating that PDF for future tech and new artists, as well.
Every artist here who hasn’t done so already: download it! Now!
